I read about people removing the middle layer from their OEM headgasket to gain a little compression, but I wanted to see how safe that actually is. The goal of the motor is 200whp NA (H23)

 

Anyone?

 

Whats your setup going to be?

 

actually some people run just one of the layers. corey jacobs ran that on his h22 and told me he never had any headgasket related issues. I'll be looking further into this this spring

 

Currently short ram intake, OBX header, 2.5" catback exhaust, Magnaflow cat, 12lb flywheel, Crower Stage 1 cams with DarkStar gears, MaxBore throttle body and port matched intake manifold. When I take the head off, I'm gonna do a light P&P. Will removing the middle layer put me at 10:1? Or 9.9:1 (stock is 9.8:1, right?)?

 

That will not get you near 200hp in an h23.

 

why not just buy a thinner gasket in the first place.

 

find me one company that makes one.

research before you type.

 

I don't think it'll be much of a problem removing the middle layer. I know a lot of people that do that on b-series engines without adverse effects. Don't really hear it much with the H series so I can't say for sure, but the concept is the same.

 

http://www.cometic.com can do custom head gaskets in many sizes.

I am sure many any manufacturers will too, helps if you do a lil research, or use google.

Their headgaskets are the best. I ran one on a built B18 back in the day. It was a nice gasket.

I had to go back and re-read that he was talking about an H23. (H23a1?)

With your goals, you're going to have to do alot more to the motor than the basic bolt ons. If you're really serious, you'll most likely have to run forged pistons, which will require new sleeves. There's no need to use a thinner head gasket if you plan your build correctly the first time. Get a set of custom forged pistons that will make up your desired CR, instead of trying to take short cuts and potentially ruin your motor. Just my $0.02.

obviously you have never dealt with them because they only offer gaskets OEM thickness or THICKER (for boost applications)

nice job

Have you ever heard of gasket failure on a H seires due to running a thinner gasket?? It seems like a cost effective mod that actually works with no adverse effects as long as its installed correctly. If he had a few grand lying around to sleeve the block, he would probably just get an H22.

 

I would suggest h23 vtec with type s pistons and some good headwork and tuning. That would be the best bang for your buck imo. Modifying the headgasket is not the best way to increase compresion.

based on what specific information/experieces? When have YOU personally seen any issues from a thinner headgasket that was installed correctly? If you're going to make a claim you should be able to back it up.

 

you can pull the middle layer out.

 

Hey dont be so quick to be a dick. I didnt say that you couldnt do it I said it was not your best route. Why do all the work taking the head off just to get .1 compression points. What experiences do you have please share. I happen to be an automotive engineering student so explain why you are more experienced than I am, and please tell me where you get your information to back up your claim.

As it turns out I have a bachelors in mechanical engineering and I'm well on my way towards a masters degree...however this has nothing to do with the topic.

You claim that running a thinner gasket is bad, I simply asked for evidence to support your claim. There is alot of bad info on h-t because people like to talk about things when they have no first hand experience. I have talked to people that use thin gaskets and researched it... only to find that it is a very cost effective way to slightly increase compression. If you would have read his setup, he plans on doing a port and polish so the head is coming off anyways.

 

I didnt say it wouldn't work i said there are better ways to get compresion. There was no need for you to be an *******. If all you were doing was bumbing compression .1 point you wouldn't even notice the difference, and sure as hell wouldn't make 200hp. And i beleive you asked me what my experience was and where my knowledge comes from.

 

But he didn't ask what you thought of the mod, he asked if it was safe. You implied that it was not. I called you out and you couldn't prove your point. Everyone knows that its not going to make a wold of difference, but every little bit helps. Nobody asked for your OPINION so don't state it as a fact, that's how people learn wrong information.

 

Quote when I said that it was not safe. What have you proven exactly. I'm sure there is absolutely no reason why honda uses the gasket that they do.
